The Taco SmartPlug Instant Hot Water Control
®
is designed to upgrade
any hot water recirculation system. SmartPlug replaces inefficient
timers and aquastats typically used in recirculation systems. It adds
intelligence to your system by learning when hot water is used in the
home. The pipe-mounted sensor records daily hot water usage pat-
terns during the course of the week. Recorded data is used to auto-
matically run the circulator at the same times the following week. So
hot water is awlays available when it is needed. If usage pattern
changes, the SmartPlug adjusts automatically.
Upgrades any hot water recirculation pump with a
powercord, to “Smart” operation.
The average residence can save up to
12,000 gallons of water per year by eliminating the wait for hot
water to arrive at fixtures and taps.
Hot water is available in seconds. No
timers or programming required.
“Smart” setting maximizes hot water comfort and energy sav-
ings.
The SmartPlug, when combined with a Taco domestic
hot water circulator, provides whisper quiet operation and industry
leading electronics for proven performance and dependability.
“Smart” When set to Smart mode, the SmartPlug will run in
Pulse mode as described below for the first 7 days of operation.
During the first 7 days, the SmartPlug monitors and records the
home's hot water usage pattern. For the following 7 days, the
SmartPlug will use the preceding week's usage pattern to cycle the
pump during the recorded hot water usage times. This process of
recording and repeating is continuous, and automatically adjusts the
pump "ON" times to match the house hold's usage pattern.
When set to Pulse mode, the SmartPlug will cycle the
circulator pump "ON" for 5 minutes, then “OFF” for 10 minutes to
maintain hot water at all faucets and taps. It will repeat the cycle con-
tinuously.
1. The SmartPlug is designed for use with standard domestic hot
water circulators that have a 120V UL approved line cord. CON-
SULT TACO, INC. BEFORE USING SMARTPLUG WITH A CIR-
CULATOR THAT IS NOT MANUFACTURED BY TACO.
2. Unplug the circulator from the 120V wall outlet.
3. Using the black sensor strap provided, attach the SmartPlug sen-
sor to the HOT water supply pipe from the hot water heater. USE
EXTREME CAUTION WHEN INSTALLING THE TEMPERA-
TURE SENSOR ON THE HOT WATER SUPPLY PIPE AS PIPE
TEMPERATURE MAY BE EXTREMELY HOT. The sensor must
be strapped at least 18" away from the hot water source to
ensure proper sensor temperature readings. The "flat" side of the
sensor should be strapped directly to the hot water supply pipe
using the black sensor strap provided. If the supply pipe is insu-
lated it will be necessary to remove the insulation at the point
where the sensor is installed to ensure accurate sensor readings.

. Install the SmartPlug temperature sensor. Connect the 2 wire
leads on the temperature sensor to the green sensor connector
terminal block by loosening the 2 set screws. Insert the 2 wire
leads from the temperature sensor into the terminal slots on the
t
erminal connector and tighten the 2 set screws. Be careful not
to over tighten screws as you may damage the terminal connec-
tor. Once the temperature sensor wires are securely fastened,
insert the terminal block into the SmartPlug receptacle labeled
"SENSOR". NOTE: The SmartPlug sensor is provided with a 10'
lead wire. Some installations may require a sensor lead wire in
excess of 10'. If the sensor lead length needs to be increased,
standard "18 AWG" gage wire and 2 wire nuts can be spliced into
the temperature sensor lead wires to extend the overall length.
5. Plug the SmartPlug into a properly grounded 120V wall outlet.
LED’s will illuminate and a 10 second diagnostic check will begin.
6. Plug the circulator 120V line cord into the 3 prong receptacle on
the face of the SmartPlug. NOTE: The circulator must be a prop-
erly grounded 120V pump. The green POWER LED will illuminate.
7. If circulator is equipped with a timer, turn the switch to full ON
position. SmartPlug will turn the circulator on after a 10 minute
delay.
1. The SmartPlug has a "Mode Select" push button that allows for
2 operation modes. "Smart" or "Pulse" mode can be selected by
pressing the mode select button located on the lower right side
of the control box. To set the mode, make sure the SmartPlug is
plugged into a properly grounded 120V outlet. A yellow LED
labeled "MODE" on the face of the SmartPlug identifies the mode
selected.
Smart Mode:
Solid Yellow LED
Pulse Mode: Blinking Yellow LED
Press and release the mode select button once to change the
mode.
2. The SmartPlug is also provided with a red "SENSOR" LED. If the
sensor is properly installed the SENSOR LED will not illuminate.
If the red LED is flashing, refer to the troubleshooting section
below.
3. Installation and mode selection are complete.
4. To ensure the SmartPlug is providing hot water properly, open a
hot water tap at the fixture furthest away from the hot water tank.
Use CAUTION as the water may be extremely hot.
OTHER UNIQUE FEATURES:
Vacation Mode: After 36 hours of no hot water usage, the
SmartPlug will automatically turn the pump OFF, and will restart
when hot water usage is detected.
Exercise Function: While in vacation mode, the SmartPlug will
cycle the pump for 10 seconds every 7 days to prevent corrosion
or scale buildup.
